HAY-PRESS.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed April 6,1906. Serial No. 810,364.

To (LZZ whom, it may concern Be it known that I, J osnrn W ALSON Care TER, a citizen of the United States and over the age of twenty-one years, and residing at Roseburg, Douglas county, State of Oregon, have invented a new and useful Improvement in Hay-Presses, of which the following is a specification, to wit:

My invention relates to improvements in presses forbaling hay or the like, and consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

One object of the invention is to provide a light and compact machine of this character in which the power is applied directly to the plunger in a very simple manner and with very effective results.

Another object of the invention is to provide an improved self -feeding device which is operated automatically as the plunger of the press is reciprocated.

The above and other objects are accomplished by the improved construction illustrated in the accompanying drawings, in which Figure 1 is a perspective of my improved hay-press, showing the feeding device in its closed position in full lines and in its open position in dotted lines. Fig. 2 is a similar view of the opposite side of the press, showing the manner in which the plunger is operated; and Fig. 3 is a detail vertical longitudinal section also showing the operation of the plunger.

In the drawings the numeral 1 denotes the framework of the press, consisting of upper and lower longitudinal beams 2 3, connected by uprights 4 and by suitable cross-beams 5.

Mounted in suitable bearings upon the lower beams or timbers 3 is a transverselydisposed main drive-shaft 6, to which power is transmitted in any suitable manner from a gasolene-engine or other motor.

On the shaft 6 is a sprocket-pinion 7, connected by a sprocket-chain 8 to a sprocketgear 9, loosely mounted upon a transverse shaft'lO, but adapted to be locked to rotate therewith by a clutch 11 ofv any suitable form.

The shaft is mounted in suitable bearings upon the upper beams 2 and has fixed upon its portion between said beams 2 cogwheels or pinions 12, which mesh with larger antifriction-rollers 17 18, which are adapted to successively engage laterally-arranged angular shoulders 19 20, carried by theplungerrod 21 of the press. The plunger-rod has its inner end suitably fixed to the plunger-head 22, and it is adapted to slide through a guide 23, as clearly shown in Fig. 2. The plunger is moved outwardly by a spring 24 of any suitable form and construction, and it is forced inwardly by the engagement of the rollers 17 18 with the shoulders 19 20. The latter are formed by suitably bending, as shown in Fig. 3, a metal strap 25, which is secured upon the top of the plunger-rod 21 and has its inner end secured, as at 26, to the head-block 22. The wrist or crank pins 15 16 and the shoulders 19 are so arranged that as the gears 13 rotate in the direction of the arrow in Fig. 3 the roller 17 will first engage the shou'der 19 and force the plunger inwardly through a portion of its stroke, and when the roller 17 leaves said shoulder 19 the roller 18 will engage the shoulder 20 and force the plunger inwardly through the re maining portion of its stroke. As the roller 18 leaves the shoulder 20 the spring 24 will pull the plunger outwardly into such position that the roller 17 will again engage the shoulder 19 as the gears 13 revolve. Thus the plunger will be reciprocated once for each rotation of the gears 13, and it will therefore be seen that the speed of the machine may be regulated by varying the relative proportions of the wheels 12 13.

The self-feeding device comprises two transverse shafts 27 28, mounted in suitable bearings in the upper portion of the frame 1 and at the ends of its inlet-opening. Upon the shafts are fixedrows of fingers 29, which are so spaced apart that the lingers on one shaft will pass between the fingers upon the other when said fingers are swung downwardly, as shown in full lines in Fig. 1.

Upon the outer ends of the shafts 27 28 are fixed crank-arms 30, winch are connected by links 31 to one end of a lever 32. The latter is suitably pivoted intermediate its ends, at 33, and has its opposite end 34 beveled and adapted to be engaged by a pin or stud 35, projecting from a crank-arm 36, fixed upon one end of the shaft 14. The crank-pin 35 actuates the lever 32 in one direction, and. it is actuated in the opposite direction by a coil-spring 37, connected at one of its ends to the lower portion of the frame 1 and at its opposite end to the end of said lever. It will be seen that as the shaft 14 rotates the crank-pin 85 will engage the bottom edge of v the lever 32 and swing it against the tension of'the spring 37, so that the links 31 are drawn downwardly, and the feeding-fingers 29 are swung downwardly to press the hay between them through the feeding-opening in the top of the press. hen the beveled end 34 of the lever 32 slips off of the crank-pin 35, the spring 37 pulls the lever from its full-line to its dotted-line position in Fig. 1, so that the links 34 are forced upwardly and the fingers 29 elevated, as shown in dotted lines in said figure. It will thus be seen that this operation of the feeder takes place conjointly with each stroke of the plunger of the press.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1; In a baling-press, a main frame, a longitudinally-extending reciprocatory plungerrod slidably mounted in the lower central portion thereof, a head upon the inner end of said rod, the metal strap 25 arranged upon the top of said rod. and bent upon. itself to provide the shoulders 19 and 20, one end of said strap being secured to the rod. and its other end to said head and forming a brace therefor, a spring for retracting said plungerrod, a transverse shaft mounted in said frame above said plunger-rod, a pair of gears fixed i upon said. shaft and arranged upon opposite sides of said plunger-rod, wrist-plns rigidly connecting said gears and arranged at equal friction-rollers upon said wrist-pins and adapted to successively engage said shoulders 19, 20, a second transverse shaft 1nount ed in the upper portion of the frame, pinions fixed upon said second shaft and in mesh with said gears, a main drive-shaft mounted in the lower portion of said frame, sprocketchain gearing between said main drive-shaft and said second or upper transverse shaft, and a clutch connection between the latter as shown and described. 2. In a baling-press, a casing having a feed opening in its top, transverse shafts arranged at the ends of said feedopenings, rows of spaced fingers projecting radially from said shafts, the fingers on one shaft being adapted to swing between those on the other, crankarms upon the ends of said shafts, a lever pivoted intermediate its ends, links connecting one end of said lever to said crank-arms, a plunger mounted to reciprocate beneath the feed-opening of said casing, a main shaft, driving connections between the latter and said plunger, an arm upon said main shaft, a pin projecting from said arm and adapted to engage the free end of said lever to elevate the same and swing said fingers downwardly to their closed position, and a coil-spring between said frame and. the free end of said lever for pullin the latter downwardly and elevating said fingers to their open position, substantially as shown and described.
